Microsoft sues Kyocera for patent infringement, seeks sales injunction

Last updated:

Microsoft sued Kyocera for patent infringement on Friday, alleging the Japanese company’s Duraforce, Hydro and Brigadier cell phone lines violate seven Microsoft patents.

Microsoft asked a Seattle federal judge to impose a US sales injunction against Kyocera’s infringing products, according to the lawsuit.

In its lawsuit, Microsoft accuses Kyocera of using patented technology including location services and text messaging.  The seven patents-in-suit are as follows:

  1. U.S. PatentRE40,989 on “atomic operations on data structures”
  2. U.S. Patent No. 7,137,117 on “dynamically variable idle time thread scheduling “
  3. U.S. Patent No. 7,289,102 on a “method and apparatus using multiple sensors in a device with a display”
  4. U.S. Patent No. 6,349,344 on “combining multiple Java class files into a run-time image”
  5. U.S. Patent No. 7,062,274 on “increasing the level of automation when establishing and managing network connections”
  6. U.S. Patent No. 7,062,715 on “supplying notifications related to supply and consumption of user context data”
  7. U.S. Patent No. 7,050,408 on “communicating multi-part messages between cellular devices using a standardized interface”

A Kyocera representative could not immediately be reached for comment.

Microsoft deputy general counsel David Howard said  in a statement.

“We respect Kyocera but we believe they need to license the patented technology they are using. We’re hopeful this case can be resolved amicably,”

The case in US District Court, Western District of Washington is Microsoft Technology Licensing LLC vs. Kyocera and Kyocera Communications Inc.
